Hydrogen power is slowly but surely making its way into the motorsport industry, with hydrogen racecars already participating in prestigious events like the Fuji 24 hours, hillclimbs, and the Dakar Rally. The future looks promising with the announcement of the world's first hydrogen championship, Extreme H, set for 2025, and plans for hydrogen prototypes to compete at the Le Mans 24 hours by 2027. Teams are gravitating towards hydrogen as an alternative to fossil fuels due to its abundance, higher energy output compared to gasoline, and the fact that it only emits water and heat when used in vehicles, ensuring zero carbon emissions at the tailpipe. The article delves into the comparison between hydrogen combustion and hydrogen fuel cell technologies for motorsport applications, outlining their advantages and operational mechanisms. While hydrogen combustion offers high flame speeds and fast combustion ideal for racing, hydrogen fuel cells provide efficiencies at low-load conditions and zero emissions. However, challenges exist in storing hydrogen on racecars, primarily due to its high expansion ratio, which makes volume storage a major issue. The article explores the potential of using liquid or solid hydrogen for better storage capabilities, highlighting the trade-offs and challenges associated with each option. Overall, the sentiment towards hydrogen power in motorsport is positive, with a focus on innovation, sustainability, and the potential for a cleaner racing future.
